The line-of-sight structure of the field number 9. The data consist of the density values within the modelled 5.3′ × 5.3′ area, along the full 10 pc distance through the Cloud II cloud. The upper image shows that density averaged over one direction perpendicular to the line-of-sight. The lower plot shows the mean density as the function of line-of-sight distance. The main structure is a filament with the long axis at ~30 degree angle with respect to the line-of-sight.
